, 6 Claims. l

The invention relates to improvements in wands and more particularly toan improved structure of wands having a light-in-weight hollow handleportion and a comparatively heavy tip orend.

Whereas the present inventionis particularly applicable; to hollowwandsof the type generally used by magicians, certain novel features thereofare adapted, to be incorporated in the structure of tubular canes,jointed rods, and the like.

In hollow wandsof the form used by magicians it is desirable that asolid tip, or end, be rapidly and readily removable and as rapidly andreadily applied to, andfirmly secured to, the handle portion. It islikewise desirable to releasably but firmly attach ajhandle to a tubularcane, or to releasably join together the portions of a jointed rod orpointer. One object of this invention is to provide novel means toreleasably and tightly join together a handle, or a tip portion, to ahollow cane, pointer, or to a handle portion, respectively.

Another object is to provide a wand, cane, or pointer, composed of twosections which are of such structure that by rotation of one sectionrelatively to the other they will become releasably and tightly joinedtogether.

Still another object is to provide means to tightly, but releasably,join together a cylindricalhandle, or tip, to a hollow cylindricalmember constructed by rolling a strip of paper or like material into atube,

A further object is to provide an improved wand, or the like, which willbe relatively inexpensiveto manufacture, simple in construction,practical, pleasing in appearance, and very efiicient and durable inuse.

With these and other objects in view, which will appear as thedescription proceeds, there have been illustrated in the accompanyingdrawing three forms in which the features and principles of thisinvention may be embodied in pracother modified form of wand or likearticlej and strip, of thin material such as paper, or the like,

intoahollowtube, or cylinder v The outer layers I2 of the sheet ofmaterial fo-rmingthe tube are secured together by paste, or glue tostiffen it", and the outer surface may be covered with a coating ofpaint, or other like material, to color the same. The inner layers I 3of'the'material forming the tubeare left loose for a purpose to behereinafter described, 3 5

In the case of a wand acylindrical tip [4 isattached to one end of thehollow section I! while in the case of a cane the portion I4 would bethe handle while the hollow section I! would be the cane body. Obviouslyin the case of. ajointed rod the tip portion Mwould be one of thesections while the portion ll would be another. The wand tip l4illustrated in the drawing comprises a cylindrical member 15 having acap l6 coveringits inner end portion I1 and withits outer end portion 13adaptedto freely enter one end of the tubularsection II. Arelativelyshah low slot is is provided in the end portion I8 of themember I5 extending diametricallyacross the end face thereof. A shortlength of loosely twisted string 20, preferably cotton, is tightlycompressed into the slot IS with its ends'ZZ and 23 extending substantiallyequally at each side of the end portion'IS of the member 15and lying between the inner layers l3 of the tube H and this portion I8,when said portion I8 is inserted into said tube I l.

A relative rotation of the member l5 and the tube II, when the portionl8 of the former is in the latter, will cause the inner layers [3 of thetube II to be tightly wrapped upon the portion l8 to releasably securethe tube H to the tip [4. By makin the string ends 22 and 23substantially as long as the length of the portion l8 only a slightrelative rotation is required, approximately one-quarter of a turn. Areverse rotation will unwrap the layers I 3 from the portion 18 wherebythe tip I4 may be drawn away from the tube H to withdraw the'portion I8therefrom.

The string 28, due to its action on the layers 13 of the materialconstituting the tube H, may

be termed a friction imposing means as it triotionally engages theinnermost layer I3 to wrap it tightly upon'the tip portion I8 to firmlylock as rubber or like material.

through a hole 25 provided in the end portion 26 of a wand tip, canehandle, or section of a jointed 3 the tip 14 to the tube II. In the formshown in Figures 4 and5 the friction imposing means is constituted by aplug24 of resilient material such The plug 24 extends rod andfrictionally. engages the innermost layer 13 of the material of thetubell. In the form shown in Figures 6 and 7 the friction imposing.meansis constituted by astrip 21 of felt, rubber,

fabric, or like materials. The strip 21 is prefer? the surface of theportion 18 andlikewise two" ably seated in a groove 28 provided in thepor i, 1

v 4 7 tubular member totightly wrap said inner layer upon thecylindrical member and secure the members together, when one member isrotated relatively. to the other. i I

3. In an article of manufacture, the combination of a tubular memberconstructed by tightly rolling a sheet of material into a tube, theouter 7 layers being bound together by an adhesive and the inner layersbeing left loose as rolled, a cylin- V cal member and in frictionalengagement with strips 2'! maybe used diametrically opposite as Vshownin Figure '7.

It will be understood that the novel features and principles of thisinvention may be embodied in other specific forms without departing fromthe spirit and essential attributes thereof, and it is therefore desiredthat the present embodiments be considered in all respects asillustrative and not restrictive, reference'being had to the claimsrather than to the foregoing description to indicate the scope of thisinvention.
